TY - CHAP M1 - Book, Section TI - Choosing a Sample A1 - Portney, Leslie G. Y1 - 2020 N1 - T2 - Foundations of Clinical Research: Applications to Evidence-Based Practice, 4e AB - Our daily lives are filled with generalizations. Cook a good steak and decide if it’s done by tasting a small piece—you don’t eat the whole steak. Try out a new therapy with one patient and decide if you will use it again based on its effectiveness—you don’t test it on every patient. Researchers use this same principle in studying interventions, tests, and relationships. They obtain data on a group of subjects to make generalizations about what will happen to others with similar characteristics in a similar situation. To make this process work, we have to develop a plan to select appropriate individuals for a sample in a way that will allow us to extrapolate beyond that group’s performance for the application of research evidence to others.
